PLAY
accessibility
Refers to the varying levels that define what a user can access, view, or perform when operating a system.
administrator access
Unrestricted access to the entire system.
agile MIS infrastructure
Includes the hardware, software, and telecommunications equipment that, when combined, provides the underlying foundation to support the organization's goals.
availability
Refers to the time frames when the system is operational.
backup
An exact copy of a system's information.
business continuity plan (BCP)
Details how a company recovers and restores critical business operations and systems after a disaster or extended disruption.
capacity planning
Determines future environmental infrastructure requirements to ensure high-quality system performance.
client
A computer designed to request information from a server.
cloud computing
Refers to the use of resources and applications hosted remotely on the Internet.
cold site
A separate facility that does not have anyt computer equipment but is a place where employees can move after a disaster.
corporate social responsibility
Companies' acknowledged responsibility to society.
date center
A facility used to house management information systems and associated components, such as telecommunications and storage systems.
disaster recovery cost curve
Charts the cost to the company of the unavailability of information and technology and the cost to the company of recovering from a disaster over time.
disaster recovery plan
A detailed process for recovering information or a system in the even of a catastrophic disaster.
emergency notification service
An infrastructure built for notifying people in the event of an emergency.
enterprise architect
A person grounded in technology, fluent in business, and able to provide the important bridge between MIS and the business.
ewaste
Refers to discarded, obsolete, or broken electronic devices.
failback
Occurs when the primary machine recovers and resumes operations, taking over from the secondary server.
failover
A specific type of fault tolerance, occurs when a redundant storage server offers and exact replica of the real-time data, and if the primary server crashes the users are automatically directed to the secondary server or backup server.
fault tolerance
A general concept that a system has the ability to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over with no loss of service.
grid computing
A collection of computers, often geographically dispersed, that are coordinated to solve a problem.
hardware
Consists of the physical devices associated with a computer system.
high availability
Occurs when a system is continuously operational at all times.
hot site
A serpate and fully euqipped facility where the company can move immediately after a disaster and resume business.
information MIS infrastructure
Identifies where and how important information, such as customer records, is maintained and secured.
infrastructure as a service (IaaS)
A service that delvers hardware networking capabilities, including the use of servers, networking, and storage over the cloud using a pay-per-use revenure model.
maintainability (or flexibility)
Refers to how quickly a system can transform to support environmental changes.
MIS infrastructure
Includes the plans for how a firm will build, deploy, use, and share its data, processes, and MIS assets.
Moore's Law
Refers to the computer chip performance per dollar doubling every 18 months.
performance
Measures how quickly a system performs a process or transaction.
platform as a service (PaaS)
Supports the deployment of entire systems including hardware, networking, and applications using a pay-per-use revenue model.
portability
Refers to the ability of an application to operate on different devices or software platforms, such as different operating systems.
recovery
The ability to get a system up and running in the event of a system crash or failure that includes restoring the information backup.
reliability (or accuracy)
Ensures a system is functioning correctly and providing accurate information.
